Answer 1

To calculate Teresa's percent error in estimating the height of the giraffe, we first need to determine the absolute error, which is the difference between the estimated value and the actual value. Teresa estimated the giraffe's height to be 18 feet, while the actual height is 16 feet. The absolute error can be calculated as follows:

Absolute Error = |Estimated Value - Actual Value| = |18 feet - 16 feet| = 2 feet.

Next, we find the percent error by using the formula:

Percent Error = (Absolute Error / Actual Value) × 100%.

Substituting the absolute error and the actual value:

Percent Error = (2 feet / 16 feet) × 100% = 0.125 × 100% = 12.5%.

Thus, Teresa's percent error in her estimation of the giraffe's height is 12.5%.
